Abstract

The invention relates to a preparation method of non-benzene odor-less type scratch-resistant polyurethane woodware light white finish which is composed of a component A and a component B in a weight ratio of 1 to 0.5, wherein the component A consists of non-benzene odor-less type alkyd resin, acrylic resin, aldehyde-ketone resin, titanium dioxide, a dispersing agent, an anti-yellowing agent, a chelation flatting agent, a defoaming agent, an anti-settling agent and a solvent; the component B is a non-benzene curing agent which mainly comprises TDI (toluene diisocynate), HDI (hexamethylene diisocyanate) tripolymer or an addition product. The odor-less type PU (polyurethane) light white finish prepared by the preparation method does not contain aromatic hydrocarbon aldehyde ketone and heavy metals, and does not have smell residue after being varnished for 48 hours. A varnished film is high in gloss, as beautiful as a white jade, crystal clear and thick and textured, has decorative effects of being smooth and as bright as a mirror, so that a clean, elegant, simple and quiet space is created to bring relaxed and happy unique enjoyment for a user, and thus, the non-benzene odor-less type scratch-resistant polyurethane woodware light white finish is very popular to the market and a client. Besides, the non-benzene odor-less type scratch-resistant polyurethane woodware light white finish is widely applied to surface protection and decoration of products such as woodware, metals and plastics.

Description

technical field [0001] The invention relates to a preparation method of a two-component polyurethane glossy white finish for woodware, in particular to an environment-friendly, benzene-free, odor-free, anti-scratch two-component polyurethane glossy white finish for woodware.
